 After the Ada Bridge across the Sava was finished in 2012, a major "Radnička" interchange was built above the river's mouth into the Čukarica Bay.Within the projects of the optimizing the bridge's function since then, there are some changes concerning the river itself.Within the scope of the construction of the new tram routes across the bridge, the already existing tram bridge across the Topčiderka will be removed but the pillars will be preserved and used for the new track bridge.
